The Palace is a graphical chat program that has been around since about 1995. I started using it in 1998, and it is so awesome!
I am providing links to other websites, as I do not have much about The Palace here on this site.
The Palace Information - my website about The Palace
Palace Tools - A website with links to most, if not all, the palace servers in existence. They also have many links to different palace-related resources. Yay!
